beaker
A beaker is a common laboratory container used to hold, mix, and heat liquids. Typically made of glass or plastic, it has a cylindrical shape with a flat bottom for stable placement and a lip for pouring. Beakers come in various sizes and often feature measurement markings to estimate liquid volume, although these are not as precise as other measuring instruments. They are versatile tools essential for experiments, allowing scientists to easily handle, combine, or heat substances safely during research or analysis.
